By modern salmon fishing I mean the present-day form of fishing from a canoe on Canadian rivers, for in Scotland, where a man must wade or fish from the bank and is often obliged to cast a very long line, the modern light rods would be of poor service.
In canoe fishing the sport is made easy, for after a fish is hooked the canoe may be moved about and you are quickly placed below your fish, or should the fish take down stream you may follow him on his mad career.
In this form of fishing you seldom have to cast a fly more than twenty-five yards. The length and weight of a rod depend on the distance it is necessary to cast a fly, for after hooking a fish it is a very easy matter to end the struggle in short order if you understand handling fish, for a fresh run salmon, though active, is not a strong fighting fish for its weight.
Some of the old-time anglers still use the English wooden rods of sixteen feet or more in length, for they maintain that they are superior to the modern light split bamboo grilse rod. Their theory is that the latter is too quick in action and loses many striking fish, which it should not do if the rod is handled with the light hand that it is not possible to employ with a heavy rod. I find the green-heart rod is superior in a strong wind, for it has more power.
The wooden rod, though more brutal when you first give the fish the butt, is not nearly so killing, for every fibre in the bamboo is alive and at work all the time.
The modern split bamboo grilse rods now in use are fourteen feet, more or less, in length and are easy to handle for they are well balanced and weigh from 16 to 24 ounces.
My advice to a beginner using these rods is to banish the idea that the salmon rod is a two-handed rod, and always to bear in mind the fact that the right arm and the rod are as one. No amount of energy applied to the rod by the left hand will communicate itself to the line. The left hand is employed as a help in holding the rod, in fact is simply a rod-rest.
By grasping the rod firmly with the right hand at the upper end of the cork handle, with the thumb along the rod, the energy of the right arm is communicated to the rod. You cannot use the full spring of the rod unless it is firmly held. This may not be necessary for a short cast but for a long line it is imperative.
After lifting the line from the water for the back cast a flip of the left thumb to the butt at the right moment is all that is necessary, the forward cast being made with the right hand only.
